The 8866 thermal conductivity analyzer allows accurate and continuous analysis of a binary (two‑component) mixture. All zero-based ranges and suppressed ranges from 20 to 90% have air-filled sealed reference cell. It’s necessary, for suppressed ranges from 95%, using reference cell (4 ports) with a constant flow of 100% of the measuring. For intermediate ranges (50-94%) it’s alternative the use of the first or second solution.
The 8866 is an high accuracy analyzer (class of accuracy better than 1%). For this reason the inner sensing unit is temperature controlled in order to be completely insensitive to ambient temperature variations.
